ice packs

Brenda is probably already aware of this having had babies at home, but the rest of you might be interested:

you can make your own squishy ice packs for injuries by adding rubbing alcohol to water in a ratio of 1:2 in a zip lock bag and freezing. Or you can fill a ziplock baggie 1/2 with dish soap and freeze.

I suggest double bagging.

Mine lasted years until we moved and I threw them away. The ones I've made recently won't last as long because I didn't have any top quality bags.
